红帽全球峰会21.5. 验证镜像签名
您可以启用镜像签名验证，以确保在 Compute 服务(nova)启动实例前，镜像服务(glance)镜像不包含未经授权的更改。启用这个功能后，您可以防止新实例启动，其中可能包括恶意软件或安全漏洞。
注意
如果您使用没有签名的镜像创建实例，则镜像会失败，且实例不会启动。有关签名镜像的更多信息，请参阅签名镜像。
先决条件
- 已安装 Red Hat OpenStack Platform director 环境。
- 以 stack 身份登录 director。
流程
在 heat 模板中，通过将
True的值设置为VerifyGlanceSignatures参数来启用实例签名验证：parameter_defaults: VerifyGlanceSignatures: Trueparameter_defaults: VerifyGlanceSignatures: TrueCopy to Clipboard Copied! Toggle word wrap Toggle overflow -
确保用于修改
VerifyGlanceSignatures参数的模板包含在openstack overcloud deploy脚本中，然后重新运行部署脚本。
